Application filed January 30, 1928, Serial No. 250,593, and in GermanyFebruary 5, 1927.

It is known that in thev manufacture of artificial silk of viscose thefinished strands of the raw silk, after having been washed for the firsttime, are subjected to a drying process and, simultaneously therewith,to tension, the skeins being supported on bars while the drying proceedsand these bars, be-

panying drawing on which Figure 1 is a sideing supported singly ontravelling frames, or straining trucks respectively. Placing the barsupon said frames or trucks is a work which easily entails mechanicaldamage to the threads or skeins of the artificial silk, and besides, thecomplete charging of a frame which is to receive as large a number ofskeins as possible requires a certain time so that always acomparatively large number must be available in, order to prevent interruptions of the regular work.

The present invention relates to a straining truck in which the partcarrying the bars with the skeins is formed by a separate frame wherebyit is rendered possible to charge any desired number of such framesoutside the straining truck and to interchange quickly a frame withskeins to be treated for a frame with treated skeins. Another advantageresides therein that the separate interchangeable frames can be usedalso in. the preceding.

working phases, as well as in the subse uent ones, so that the bars withthe skeins nee not be removed from one place and conveyed to anotherplace but remain located upon the respective frameor frames, wherebyloss of time, as well as damage to the ware, is

' completely prevented. The interchangeable frames need not be designedfor particularly, great'stress as they can be supported upon the truckson rails extending along the entire length of the trucks so that theframes are not in the least subjected to bending stress.

The invention is illustrated diagrammatically and by wayv of example onthe accomview of an interchangeable straining frame designed accordingto this invention, and Fi 'ure 2 is a frontal view of the same.

n-the drawing, 1 denotes the interchangeable frame proper, 2 the barscarrying the skeins of the artificial silk, 3 these skeins, 4 weightingbars by which the skeins are kept straight in vertical direction, and 5denotes rails supporting the frame 2 whereby these latter are securelyprevented from bending through. There are upper rails 5 and lower,

a spreading mechanism by which the lower bars can be moved downwardly soas to subject the skeins 3 to tensile strain. Said mechanism comprisesUshaped double eyes 6 secured to the rails 5 and 5, the upper doubleeyesbeing directed downwardly, the lower ones upwardly; links'7 hinged tothe upper and the lower eyes 6; double-eyes 8 connected in pairs bythreaded'sleeves 9; and a spindle 10 which is threaded where there arethe sleeves 9. The threaded portions ,of the spindle 10 are alternatelylefthand-threaded and righthand-threaded so that the sleeves 9 are movedeither towards, or away from, each other, according to the direction ofrotation of the spindle. When they are moved towards each other theskeins-are strained,

as will be clear" without a further detailed explanation.

in order to prevent the frame 1 from being ficial silk, comprising, incombination with the bars provided for receiving the threads or skeins,an interchangeable frame adapted to receive and support said bars and tobe attach'ed to, and detached from, a suitably designed travelling truckadapted to receive and support said interchangeable frame.
